DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0031] According to an embodiment of the present invention, there is provided a compact geological sample scanning system 100 for locating onsite in the mine site or field. The partially-assembled scanning system 100, without a hyperspectral imaging sensor or scanner fitted, is shown in FIG. 1.

[0032] FIG. 1a shows the assembled scanning system 100. The scanning system 100 includes a gantry stand 200. The elevated sensor (not shown) is supported by the upright stand 200. A mounting cradle 202 is provided for mounting the cradled sensor to the stand 200. The cradle 202 is releasably fastened to the top of the stand 200.

[0033] The scanning system 100 further includes a transporter 204 for linearly transporting or translating a geological sample whilst being sensed by the sensor above. Advantageously, the scanning system 100 is compact, and can be readily disassembled for transport and then re-assembled onsite in the field as described below.

[0034] The stand 200 includes four retractable legs 206 which can be retracted in pairs to compact the stand 200 for transport. Upon release of locking pins 208, each pair of slanted legs 206 can pivot relative to a Y-bracket 210 and be retracted compactly together.

[0035] The stand 200 also includes two straight bodies 212 extending up from the legs 206. The legs 206 are releasably fastened to the bodies 212 using fasteners 214, and can be released to further compact the stand 200 for transport.

[0036] The slanted legs 206 also include height-adjustable feet 216 to level the sensor on uneven ground. The stand 200 also includes a pair of rests 218, extending between the legs 206, upon which the transporter 204 can rest. The rests 218 can include guides or fasteners 220 for guiding or fastening the transporter 204.

[0037] The transporter 204 includes an elongate rail arrangement 222, and a platform carriage 224 for moving along the rail arrangement 222. The transporter 204 further includes a motor for controllably driving the carriage 224 along the rail arrangement 222. The geological sample rests on the carriage 224 as it passes under the sensor in the cradle 202 for downward scanning. Like the stand 200, the transporter 204 also includes height-adjustable feet 216 for stabilizing and levelling on uneven ground.

[0038] The scanning system 100 also includes a light for lighting the transported geological sample whilst being sensed by the sensor. The stand 200 includes a mount 226 for mounting the light to the stand 200.

[0039] FIGS. 1B-D show the compact dimensions of the scanning system 100. The erected stand 200 is less than 1500 mm high and 1000 mm wide. The transporter 204 is less than 2500 mm long. Comparable prior art systems are significantly bigger and non-modular. These known systems are built specifically to scan core samples and therefore do not have the same flexibility as the present system 100. The present system 100 is capable of packing down much smaller.

[0040] The disassembled scanning system 100 is shipped in an ISO shipping container to site. A method for setting up the geological sample scanning system 100 is now briefly described.

[0041] First, the stand 200 is erected. The retracted legs 206 are parted, and the vertical body 212 is attached to the expanded legs 206.

[0042] Next, the sensor is mounted to be supported atop the stand 200. The sensor cradle 202 is mounted to the stand 200. In turn, the sensor is mounted in the cradle 202 with its scanning beam facing downwards.

[0043] Next, the transporter 204 is located so that the transported geological sample is sensed by the sensor above. The rail arrangement 222 is placed beneath the sensor and engaged with the stand 200. The movable carriage 224 is mounted to the rail arrangement 222.

[0044] Next, a light is provided to light the geological sample transported by the transporter 204 to provide high scan quality.

[0045] Finally, the method involves height adjusting the feet 216 of the stand 200 and/or transporter 204.

[0046] The geological sample is loaded on the carriage 224 which moves beneath the elevated sensor whilst scanning.

[0047] Once testing is complete, the scanning system 100 may be readily disassembled, using the reverse steps, and transported in a shipping container once more.

[0048] A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.
